Many studies have demonstrated that those high in weight-related concerns eat more after food-cue exposure, which is consistent with predictions of the cue-reactivity model. However, the counteractive-control model predicts that exposure to fattening foods activates dieting-related goals and behavior in weight-concerned individuals. Although these models seem incongruous, the authors hypothesized that the salience of the cue could represent a critical factor in determining which model is activated. The authors predicted that attending to salient food cues would result in increased intake (cue reactivity) in individuals with high weight-related concerns, whereas incidental food-cue exposure would result in decreased intake (counteractive control), relative to control exposure. The authors employed a 3 (attended vs. incidental vs. control cue) x 2 (low vs. high weight-related concerns) design. As expected, participants with high weight-related concerns who attended to a food cue ate more than did both those with high weight-related concerns in the control condition and those with low weight-related concerns in the attended-cue condition; however, intake of individuals with high weight-related concerns who were exposed to the incidental cue did not differ from that of those in the control condition. The manner of food-cue presentation may be a critical factor in determining eating behavior. (PsycINFO Database Record (c) 2009 APA, all rights reserved).
许多研究表明,那些对体重相关问题关注度高的人在接触食物线索后会吃得更多,这与线索反应模型的预测一致。然而,反制控制模型预测,接触易胖食物会激活体重关注者与节食相关的目标和行为。尽管这些模型似乎相互矛盾,但作者假设线索的显著性可能是决定激活哪种模型的关键因素。作者预测,关注显著的食物线索会导致对体重相关问题关注度高的个体摄入量增加(线索反应),而相对于对照暴露,偶然接触食物线索会导致摄入量减少(反制控制)。作者采用了一个3(关注线索组vs.偶然线索组vs.对照线索组)×2(低体重相关关注度vs.高体重相关关注度)的设计。正如预期的那样,关注食物线索的高体重相关关注度参与者比对照条件下的高体重相关关注度参与者以及关注线索条件下的低体重相关关注度参与者吃得更多;然而,偶然接触线索的高体重相关关注度个体的摄入量与对照条件下的个体没有差异。食物线索呈现的方式可能是决定饮食行为的一个关键因素。(PsycINFO数据库记录(c)2009美国心理学会,保留所有权利)
